How to help a chick with a little yoke sack still to go.

I have a plymouth rock chick that has exited its shell before its time and has some remaining yoke still to absorb. As the picture shows its not as horrible as some posts I have seen on here but still concerning and undoubtedly uncomfortable. It is very active and vocal and I want to give it the best chance I can to make it through the next few days, what should I do!

ps.
-Its still in the incubator (brinsea) /I cleaned the incubator with antibacterial and removed the hatch waste
-Humidity was quickly back in the hatching band
-Its separated from the other chicks that have already hatched

She seems happy enough for the moment and still active, not much change in yoke intake. Its a little smaller. At 24 hours would you advise that I put her in the brooder with food and water even if the yoke isn't completely in or can she have more time in the incubator?
